No:
Any backward links that linked to the old domain name will not link to the new domain name.
You should not let desired domain names expire.
You could use a responsible domain name management company, like my company, iRapture.com, to manage your domain names so you don't let a domain name expire if you really want to keep it active.
Yes: Any keyword work in the code will be on the new site and will help the new domain name show up on yahoo, google and bing. Search engines probably do not treat a .com as better than a .org or .net.
No and, in fact you would be wasting your time.
The back links don't point to your domain and therefore wont help you, its a new domain so has zero authority and the content has already been indexed by Google and, therefore your site wont be credited as the original source. I didn't say 'duplicate content penalty' because it doesn't work this way, but you definitely wont rank doing this.
unfortunately it is not a simple question to answer properly.
It depends on whether the current site owner keeps the original content active, whether the SEs see your dot org site content as duplication...how long the SEs keep archive copies of the original content if the new site owner does not maintain the site in its current form

Hey everyone! Quick question- I used to own a website, lets call it website.com, but I no longer have access to it. So instead I bought the .org domain name, aka website.org, and I was wondering if I copied all of the contents from my old website (website.com) to the new on (website.org) and gave google a few months to rank it, would my SEO ranking for the new website be somewhat similar to the old one?
And just to clarify the only difference between the 2 domain names in the .com and .org! Thanks
